Sn with the content of 0.004% in the lithosphere is almost in presence of cassiterite and little in presence of Sn-contained sulfide. Since 1980s, the anticancer active study on organic complex compounds has attracted considerable attentions, it becomes another hot issue after the study on Pt. When time up to the year 1989, the anticancer active measurement of more than 2000 kinds of Sn-contained complex compounds have been carried out by Cancer Academy, U.S, with the results showing half of these Sn-contained complex compounds posses antileucocythemia(P388) activity. Thereafter, Sn-contained complex compounds synthesized by hydrothermal reaction also become a hot issue people focus on.

Sn在地壳中的含量为0.004%，几乎都以锡石的形式存在，此外还有极少量的Sn的硫化物。20世纪80年代以来，人们对Sn有机配合物抗癌活性的研究产生了浓厚兴趣，成为继顺铂之后又一活跃的研究热点，到1989年，美国国家癌症研究所对2000多种Sn的配合物进行了抗癌活性测定，结果表明，50%的配合物具有抗P388白血病活性，故水热溶剂热合成锡的配合物也成为人们的研究热点。
